How Will You Survive Without Drinkable Water? – Day 1


You were a passenger on an aircraft that has crash landed on a deserted island in the south Pacific Ocean. Only eight (8) of you have survived. The average temperature in the shade on the island is 90 °F.
You have scoured the wreckage of the plane and found that there appears to be no food and only 128 500-mL Poland Spring water bottles for eight (8) persons. You did find the airplane's emergency slide (which can be used as a floatable raft); however it can safely fit only four (4) people.
Reconnaissance of the small island has determined that there is no fresh drinking water supply. Rather, there appears to be a swampy, foul-smelling pool of water near the middle of the island. The ocean cannot be used since jet fuel and oil from the crash has contaminated the water beyond your ability to clean it.
A meeting of the survivors shows a clear distinction between those that believe the only chance for survival is to leave immediately on the raft with the limited water left and others who believe that they can purify the foul water using materials recovered from the crash site and the island. A compromise is reached and it is decided that four (4) people will attempt rescue by leaving the island on the raft. However, they will be taking three quarters (3/4) of the water on their journey.
Your group of four (4) will stay behind and await rescue. There is no time to waste. You have very little water and less time to figure out how to purify the water from the foul pool.
Will you survive?



Careful analysis of the wreckage shows the following materials available:


Wreckage
Chem. Lab Equivalent
1 Measuring Cup
1 - 100 mL graduated cylinder
1 Soup Bowl
1 - 150 mL beaker
1 Funnel
1 glass funnel
1 Paper Clip
1 pinch clamp
1 Styrofoam Cup
1 styrofoam cup
Coffee Machine Filters
Filter Paper
1 Pitcher
1 - 150 mL Erlenmeyer flask
Hydraulic Hose
Rubber tubing
1 Light Bulb
1 Battery

In addition, you have the following items at your disposal on the island:
Sand from the beach
Gravel from the island
Charcoal ash (leftover from your campfire)
Fire and plenty of wood

You have also figured out a way to fashion a way to place something over a fire or another object (The lab equivalent is 1 ring stand, 1 iron ring, and 1 clay triangle)

Before you begin to solve the problem, your group must first understand the rules under which it will be governed. You will first write a mutually agreeable contract that you will print and sign (See the template to work with under "Files.")
Set up a Google Group for your team and include Mr. Nilsen as a member. You will use this to enter information gathered, experiments attempted (and their rationale), and analysis of what worked, what didn't, and why, as well as your next hypothesis on how to clean the water based on previous data. This area will also be used to
Note: All work must be shown on your Google Group site.

Questions that Must be Immediately Answered:
1. How much water does one (1) human being need per day to survive on this tropical island? How much water do those remaining on the island have? How many days supply is that?
2. What will be the best way to purify the water?
3. Will you use trial and error to find a suitable means? Is there another way?

ENJOY!!!
